There was a problem with the recent update for the STO launcher (after clicking 'play' in the Steam Library). After this problem, I was only able to get to the point of entering the password, and any attempt to Login or hitting enter caused the launcher to crash.

I think the launcher got corrupted by the last update for it. How do I delete the launcher from my Steam files so I can try to download the latest oneÉ (please excuse the accented e in place of a question mark, thatès a problem of another sort).

I'd rename the STO folder in Steam, reinstall (reverify files will start it). Once you see the launcher... stop the process... make a copy of the launcher (Star Trek Online.Exe). Copy or move/rename your original STO folder, copy back in the new launcher.. tada.
